Planing a home theatre
I am building a new home in the near future, and am designing my new home theater which will go in my basement. The space I have to put it in measures 13'-8" wide, 18'-6" long, and 8' high. This space is measured to the inside of some insulated walls I will be putting against my block work and on top of an insulated floor.
My plan is to build a "room within a room", leaving a 1-2" gap between those walls and my new walls, creating a new room with inside dimensions of 12'-2"*17'-8"*7'-7".
Will this room be too small to sound good? If so, should I deviate from the ideal case of 1, 1.6, 2.33 to take up as much room as possible? Should I forget the double walls?
